Definition & Description of Mytho

“Mytho” refers to a person who lies, exaggerates, or tells dramatic stories just to impress others.
It comes from the French word “mythomane,” meaning someone who invents stories (a fabulist).

A mytho isn’t always harmful — sometimes they’re just seeking attention. But it can also describe someone who constantly lies in a way people no longer trust.

This word is especially common among teenagers, friends, and social groups where exaggeration is easily noticed.

It can be playful or a bit insulting, depending on the tone.

Examples of Mytho

  • “Il invente toujours tout. Quel mytho !”
    (He always makes stuff up. What a liar!)
  • “C’est faux ? T’es un mytho ou quoi ?”
    (Not true? Are you lying or what?)
  • “Elle adore faire sa mytho.”
    (She loves acting like a liar.)
